What are PDF Attachments?

PDF attachments allow you to embed files directly into a PDF document. This creates a single file package containing:

  • Your main PDF document
  • Additional files embedded within it
  • Support for any file type (PDF, DOC, XLS, ZIP, images, etc.)

Use cases include:

  • Attaching supporting documents to reports
  • Embedding source files with design PDFs
  • Adding certificates or licenses to contracts
  • Including spreadsheets with financial reports
  • Packaging multiple files for distribution
